BOX STUD AND NOSE GUARD FOR OPHTHALMIC MQUNTINGS Dec. 13, 1932.

Filed July 1, 1931 EWITNESSES Patented Dec. 13, 1932 UNITED STATES FFICE JAooB'J. POMERANZ, or BROOKLYN, AND vrnonnr TANASSO, or HARRISON, NEW YORK BOX STUD AND NOSE GUARD FOR OPHTHALMIC MOUNTINGS Application filed July 1,

This invention relates to ophthalmic mountings, and has particular reference to an improved means for connecting a nose guard terminal to an eye-wire or lens frame, al-

though said means may be applied to various other points of ophthalmic mountings, such as connecting the bridge spring terminal or equivalentelement to the eye-wire.

Heretofore box studs have generally consisted of a base suitably anchored to the eyewire or lens frame and provided wit-h a pro jecting shank having a box stud at the free end of the shank, which box stud is provided with a vertically disposed straight-sided opening or passage which receives the terminal portion of the nose guard, and through which box stud and nose guard a screw extends having its final anchorage in the shank. Obviously, this construction is open to many objections, notably, in many instances, the head of the screw contacts with the nose, causing discomfort to the wearer; the straight-sided opening or passage does notmake for a rigid connection of the nose guard therewith, and the general construction renders the form of connection unnecessarily prominent and unsightly.

In order to overcome the above recited and other objectionable features and disadvantages, the present invention comprehends an improved box stud which is disposed horizontally and one end of which is soldered directly to the eye-wire or lens frame to dispose itsreceiving socket for the nose guard or bridge spring terminal horizontally, hence rendering the connection unobtrusive, avoiding the positioning of the screw where it may contact with the nose and affording a less expensive mode of connection which improves the general appearance of the mounting.

More specifically, the invention resides in a box stud having a horizontally disposed laterally tapering bore which is closed at its inner end and a nose guard having a horizontal terminal formed with a corresponding taper to snugly fit the bore of the box stud whereby toprovide a more rigid and lasting connection.

As a still further object, the invention aims to provide interengaging means at the terminal of the nose guard extremity and the closed inner end of the bore for further insuring the rigidity of the connection.

The invention further resides in the use of the closed inner end of the bore of the box stud as a means for soldering said box stud to the eye-wire while excluding the possibility of the solder gaining access to the bore and preventing proper interfitting of the nose guard terminal therein. 160

With the above recited and other objects in view, reference is had to the following description and accompanying drawing, in which there is exhibited one example or embodiment of the invention, while the claims define the actual scope of the same.

In the drawing:

Figure l is a fragmentary perspective view illustrating a box stud of the improved form attached to the eye-wire and showing the 47 nose guard in broken lines, in its applied position. v

Figure 2 is an enlarged horizontal sectional view therethrough.

Figure 3 is an enlarged transverse sectional .75 view through the box stud with the nose guard removed.

Figure 4 is a plan view of the box stud blank prior to the bending of the same into its finished condition.

Referring to the drawing by characters of reference, A designates an eye-wire or lens frame, B generally the box stud, and C the nose guard. As illustrated in Figure 4 of the drawing, the box stud is formed from a blank of sheet material which is suitably shaped to provide when folded an upper horizontal wall forming portion 5 which has divergent sides 6 and lower mating wall forming portions 7 and 8, each of which is joined at the edges 9 and 10 to the side wall forming portions 11 and 12, which side wall forming portions are respectively joined at their remaining edges to the edges 6 of the upper wall forming portion 5. The mating upper wall forming portions 7 and 8 have their outer free edges 13 and 14 diverging with respect to their inner edges 9 and 10, and said outer edges are rabbeted as at 15 and 16 to provide a lap joint, fairly illustrated in Figure 3, which is designed to be soldered.

In order to close the inner reduced end of the stud B, a boss 17 is formed on the upper wall forming portion 5 and corresponding mating 5 bosses l8 and 19 are formed at their reduced inner end of the wall forming portions 8 and 9. The upper Wall forming portion 5 is formed with a screw opening 20, and the opposite edges 13 and 14 of the lower mating wall forming portions 7 and 8 are formed with mating substantially semi-circular notches 21 and 22 which when the blank is folded form a screw receiving opening aligning with the opening 20. The opening 20 is preferably threaded to receive the threaded end of the screw 23 which is designed to pass through an aperture :24 in the horizontally disposed terminal 25 of the nose guard C. The terminal 25 is formed with opposite outwardly diverging sides 26 to snugly fit within the tapered socket formed by the box stud B. In order to further assist in rigidly securing the nose guard terminal 25 within the box stud, the closed inner end of the stud formed by the bosses 17 18 and 19 and the extremity of the terminal 25 may be provided with interengaging means, such as the notch 27 and tongue 28. In practice, the notch may be formed in the nose guard terminal 25 and the tongue on the closed end of the stud within the scope of the present invention. The closed end of the stud also acts as a surface for soldering the same to the eye-wire A and precludes the entrance of solder into the receiving socket.

While the box stud has been particularly disclosed for the purpose of connecting a nose guard to an eye-wire, it is to be understood that the same may be used for other purposes, and hence, no limitation is necessarily intended to its use for connecting a nose guard to eye-wires.

What is claimed is:

1. In ophthalmic mountings, a device for anchoring a nose guard terminal to an eyewire including a box stud fashioned from sheet material to provide horizontal walls having divergent sides and joined by divergent side walls to provide a socket of inwardly decreasing width for snugly receiving a correspondingly shaped nose guard terminal.

2. In ophthalmic mountings, a device for anchoring a nose uard terminal to an eyewire including a box stud fashioned from sheet material to provide horizontal walls having divergent sides and joined by divergent side walls to provide a socket of inwardly decreasing width for snugly receiving a correspondingly shaped nose guard terminal, the horizontal walls of said stud structure having mating bosses at their narrower inner ends for closing the same to facilitate soldering of the stud to the eye-wire and functioning to exclude the solder from the socket.

3. In an ophthalmic mounting, the combination of a box stud having a horizontal inwardly tapering bore and a closed inner end and a nose guard having a horizontal terminal formed with a corresponding taper to snugly fit the bore of the box stud, the closed inner end of the bore and extremity of the nose guard terminal having interengaging portions.

4. In an ophthalmic mounting, the combination of a box stud having a horizontal inwardly tapering bore and a closed inner end and a nose guard having a horizontal terminal formed with a corresponding taper to snugly fit the bore of the box, stud, the closed inner end of the bore and extremity of the nose guard terminal having interengaging portions, said portions respectively consisting of a recess and a projection engageable in the recess.
